Tetra System
The Tetra system is a planetary system of 5 planets: Tetra 1, 2, 3, and 4, and Tetrapolis, a small planetoid that has been terraformed into a city-planet.
Tetra 1 is almost earthlike, a little larger than Earth, but has an atmosphere that most species are not adapted to breathe. The planet is covered with vast blue-green forests, but does not have any native animal life.
Tetra 2-3 are both rocky planets, both unsuitable for life. Tetra 4 is a gas giant.
